Kiwi.com MCP Server
A keyless flight search with one typed, read-only tool, 47 filters and a booking link on every itinerary. It can't book, hold, change or cancel, and it has no published rate limits, changelog, terms or version. Each search returns 15 itineraries with no way to ask for fewer.
Before you call either
FlightClaw
- Call
get_offerright beforecreate_checkout; the total includes the booking fee and can move - Poll
get_checkout_statusuntilcompleted, thenget_orderfor the airline reference. A sent link isn't a booking - Never ask for card numbers in chat. Hand over
checkout_url, or pay it with a Link virtual card the user approved for the exact total - Budget 100 searches a day per signed-in user, and use
search_multi_cityinstead of many single searches - Save the traveller once with
save_travelerso later bookings don't re-ask for passport details
Kiwi.com MCP Server
- POST to
https://mcp.kiwi.comitself./mcpreturns 404, and responses arrive astext/event-streameven for a single reply - Send dates as dd/mm/yyyy and set
currency, which defaults to EUR - Check the
errorfield of every result. A rejected input returnsresultsCount0 withisErrorfalse - Narrow with
price_to,max_sector_stopoversandsort. There is no limit parameter and each search returns 15 itineraries - Give the user
bookingUrlto book. Don't callfeedback-to-devswith user data, because it sends free text to Kiwi.com
